gold is found in archean (rocks older than 2.5 billion years) greenstone belts in australia southern africa and canada. greenstone belts are volcanic-sedimentary sequences which include ultramafic rocks dolerite basalt chert sandstone shale tuff banded iron-formation and other rock types.
what are the different types of copper ore and how are they processed? here’s a brief primer on the subject for investors. copper-containing rock or copper ore holds only a small percentage
in metallurgy a flux (derived from latin fluxus meaning "flow") is a chemical cleaning agent flowing agent or purifying agent. fluxes may have more than one function at a time. they are used in both extractive metallurgy and metal joining. some of the earliest known fluxes were carbonate of soda potash charcoal coke borax lime lead sulfide and certain minerals containing phosphorus.
sep 01 2019 0183; 32;4 different types of metals|their properties & uses. there are different types of metals based on physical and chemical properties. they are the hardest elements which are found on the earth.. most of the metals are solids in nature except for mercury which shows liquid-like motion. they are bendable into different shapes and have many uses in human life.
nature entices man into the adventure of metallurgy by an initial gift of an almost magic charm. gold the most attractive and precious of metals in every society is also the easiest for primitive man to acquire. gold is bright incorruptible malleable and appears in pure form in the beds of streams.
feldspar — feldspar is a rock-forming mineral. it is important industrially in making glass ceramics enamelware and soaps. it is also used in making bonding material for abrasive wheels cements fertilizer tarred roofing materials and as a sizing or filler in textiles and paper.
if you have a rock that contains between 1.0 and 1.8% nickel (whole-rock analysis) whether or not it appears to contain metal then the rock might be a meteorite. if you have a rock that does not contain metal and has a low concentration of nickel (<1% = <10000 ppm) it could still be a rare type of meteorite an achondrite. (about 5% of stony
well that’s obviously because gold and silver are two precious metals. that you already know… but what about other metals? there are other substances equally precious even more precious than gold that you must get to know better. so here’s a list of the top 10 most precious metals in the world.

when these magmas ascend into the earth's crust their chemical composition undergoes further changes in response to variations in pressure temperature and composition of surrounding rocks. the result is an astonishing diversity of rock types that are variably enriched in economic elements including the rare earth elements.
extractive metallurgy: the practice of removing valuable metals from an ore and refining the extracted metals into a purer form. leaching: a widely used extractive metallurgy technique which converts metals into soluble salts in aqueous media. ore: a type of rock that contains minerals with important elements including metals.
the auckland volcanic field has erupted this type of hot runny iron-rich lava and the landscape is dotted with mountains made from basalt and scoria (a red-coloured rock that contains large amounts of iron-rich minerals). both rock types are excavated for building materials and landscaping. andesite

many metals occur naturally in the form of sulfides. most of sulfides are of magmatic or hydrothermal origin but some may be present also in sedimentary rocks. typical examples are pyrite pyrrhotite chalcopyrite galena sphalerite pentlandite bornite and molybdenite. sulfides are source of widely used metals like copper lead or zinc.
